5. First we constructed the circle of inversion
and the circle to be inverted. The circle to be
inverted was constructed to go through the center
of the circle of inversion. We know that the inverse
of a circle through the center of the circle of inversion
is a line. So we found the inverses of two random points
on the circle to be inverted using a previous script and
constructed the inverse line through them.
